How it works

Appends UTM campaign parameters to any URL so Google Analytics and other tools can attribute traffic to specific sources, mediums, and campaigns.

Who it's for: Digital marketers, growth teams, and email marketers tracking campaign performance

Constructs URLs with utm_source, utm_medium, utm_campaign, and optional utm_term and utm_content.

Encodes values correctly for use in ads, newsletters, and social posts.

Produces a single trackable link ready to copy.

Enter the base landing page URL (including https://).
Fill utm_source (e.g., newsletter), utm_medium (e.g., email), and utm_campaign (e.g., spring_sale).
Add optional utm_term and utm_content for keyword or A/B creative tracking.
Copy the final URL and use it exclusively in that campaign channel.
Confirm parameters appear in your analytics reports after launch.

Use consistent lowercase naming conventions so reports do not split duplicate sources.
Do not UTM-tag internal site links—it pollutes session attribution.
Keep a spreadsheet of campaign URLs to avoid typos in medium or source names.
